# The first E2E test: signup

There is a lot to cover when writing E2E tests, and we are going to use one of the most famous examples: the signup flow. Testing this kind of flow is useful because:

- It fills a form.

- It contains an AJAX request.

- It includes some error flows to test.

- Most of the flows need a registered user.

> Note: You need to have the Conduit example running to start testing.
